できないという問題点がある。(Problem to be solved by the invention) When the disk is rotated in one arbitrary direction, the air in the vent is pushed out from the outer opening by centrifugal force, the air pressure in the vent decreases, and new air is forced into the inner opening. The inner disk and outer disk are formed from annular bodies with the same inner diameter and outer diameter, and the inner opening area of the ventilation hole is equal to the outer opening area. Since it is formed smaller, there is a problem in that the air blowing capacity is low and the expected cooling effect cannot be expected.

入しやすいように形成されている。(Embodiment) Figs. 1 to 3 show an embodiment of a ventilated disk according to the present invention, in which an inner disk 2 and an outer disk 3 are connected by a large number of ribs 1 extending in the radial direction. Both disks 2 and 3
A large number of ventilation holes 4 are provided by the and ribs 1, and the outer diameters of the inner disk 2 and outer disk 3 are the same, but the inner diameter of the inner disk 2 is larger than the inner diameter of the outer disk 3. In other words, the width of the sliding surface 2a of the inner disk 2 is formed narrower than the width of the sliding surface 3a of the outer disk 3, so that when the ventilated disk rotates, fresh air from the outside can be drawn from the inner disk 2 side. It is formed so that it can easily flow into the ventilation hole 4.

筒形のハツト部である。 The outer end of the rib 1 extending in the radial direction is formed into a bifurcated and curved shape, and the inner end of the rib 1 is curved, and a through hole 5 through which air can flow is provided at the branching part of the rib 1. Vent hole 4 through through hole 5
are communicating. 6a, 6b, and 6c are the outer openings of the vent hole 4, and 7 is the inner opening, and the area of the inner opening 7 of the vent hole is larger than the area of the outer opening 6b or the outer opening 6c. 8 is a cylindrical hat portion integrally connected to the outer disk 3.

冷却される。 When the ventilated disk is rotated in one arbitrary direction, the air in the vent hole 4 is pushed out through the outer openings 6a, 6b, 6c by centrifugal force, the air pressure in the vent hole 4 decreases, and fresh air from outside is forced out. A large amount of air is sucked into the ventilation hole 4 from the inner disk 2 side through the inner opening 7. The air flowing along the rib 1 comes into contact with the area near the through hole 5, flows out through the through hole 5 and out of the outer opening 6a, cools the area near the through hole 5, and heats the area near the through hole 5. Does not cause spots. Furthermore, most of the new air that has flowed into the vent hole 4 flows out through the outer openings 6b and 6c, and the inner disk 2 and outer disk 3 are cooled by this air.
本考案のデイスクは上述した方向と逆方向に回
転しても、上述と同様の作用を奏する。 Even when the disk of the present invention is rotated in the opposite direction to the above-mentioned direction, it exhibits the same effect as described above.

が得られる。(Effects of the invention) According to the invention, a large amount of fresh air from the outside flows into the ventilation hole from the inner disk side, and the air flowing along the rib comes into contact with the vicinity of the through hole, and the air flows through the through hole. Cooling performance is greatly improved, and heat spots do not occur near the through holes, regardless of whether the vehicle is moving forward or backward, or where the disc is installed on the front or rear wheels of the vehicle. It has a good cooling effect even if the discs are mounted on the vehicle, and since the same braking force is always generated on each disc mounted on the vehicle, a stable braking effect can be obtained.
